Based on the information you have told us:
You may be using facilities that are not compliant
Speak to your waste contractors to make sure you have the correct name for the contractor or ask them for a copy of their permits and exemptions. If they do not own the facility where your waste is taken ask them to send you the copies they hold. Otherwise you should look to change waste contractors or facilities as you face a fixed penalty notice, unlimited fine or prosecution from the relevant environment agency should the waste be sent to an illegally operating site.
